After being shown an interview of the 19-year-old from a refugee camp in northern Syria, he appeared shocked at her admission that she had seen the head of a decapitated person in a bin - and admitted she was not fazed by it.

"She saw a head in the bin?" he said.

"That makes me think twice."

Mr Hussen said he had no idea what had happened to his daughter for he had not heard from her "for quite a long time".

But he said hearing Shamima Begum's story gave him hope.

He said he would "give her a hug" if he was ever reunited with her.

Shamima Begum said she had seen two of her friends a fortnight ago, but it is not clear whether Amira Abase was one of them.
